There are several bugs in your main loop. Replace it with this one,
and it should work:

for i = 1 to length(file) do
    n = find('1', file[i])
    if n != 0 then
        x = file[i][1..n-1] & '2' & file[i][n+1..length(file[i])]
        file[i] = x
    end if
end for

You need to search for an atom ( '1' ), not a sequence ( "1" ).
Also, if the value is not found, find() will return 0, not -1.
Lastly, your replace routine is written incorrectly. The simple loop
above will work instead.
